Answer:
They are bilaterally symmetrical and have a soft body sometimes covered with a shell.
Explanation:
Mollusks are bilaterally symmetrical organisms which means only two planes can divide their bodies into two identical halves. They are triploblastic organisms with organ system level of body organization. Mollusks have a soft body that is usually covered by a dorsal shell composed mainly of calcium carbonate. The foot is a broad, flat and muscular structure located ventrally. Foot serves these organisms in locomotion. The various body organs are present as visceral mass located above the foot. The visceral mass is covered by a thin sheet of tissue called mantle. Example: clams, snails, and squids.

Answer:
dark reaction
Explanation:
The dark reactions then occur outside the thylakoid. In these reactions, the energy from ATP and NADPH is used to fix carbon dioxide (CO2). The products of this reaction are sugar molecules and various other organic molecules necessary for cell function and metabolism.
Explanation:
Photosynthesis is plants taking in water,carbon dioxide, and light to make sugar and oxygen. This is important because all living things need oxygen to survive. All producers make oxygen and sugar for the secondary consumers and then the carnivores eat animals that eat plants.
